  • Low loss partial photon number-resolution detection
    Patent number: 12247875
    Abstract: Methods are disclosed for performing projective measurements combining continuous-variable quadrature and discrete photon-number-basis detections on bosonic quantum modes. Some embodiments use single-photon detectors to perform photon subtraction on a bosonic mode propagating along a waveguide prior to field measurements with homodyne detection. Methods of implementation and specific applications for quantum computation, Gaussian boson sampling, and full quantum state tomography are also disclosed.
